As far as answering your question on crankcase strength.
The 3.0 SC engine used the identical block as for the 3.3 turbos. The rods and rod bolts are actually stronger than the turbo and later Carrera rod bolts which were downsized. You should be able to rev safely to over 7000rpm as long as valve springs are updated.
The pistons you mentioned are forged replacements, stockers are cast, good choice but make sure C/R is down to 7.5 to 1 or so for detonation protection.
You will need a modified intake manifold to add intercooling and FI already know this probably. Probably easier to start with a 3.2 Carrera manifold unit as mentioned above.
You are gonna need alot of oil cooling so get a front mount cooler that mounts below front bumper. Everything else will not get enuff airflow to cool properly.
